Irrational had a new game in the works dubbed Project Icarus. Project Icarus has been revealed as being another BioShock game dubbed BioShock: Infinite.

Set in 1912, BioShock Infinite introduces an entirely new narrative experience that lifts players out of the familiar confines of Rapture and rockets them to Columbia, an immense city in the sky.

Originally conceived as a floating symbol of American ideals at a time when the United States was emerging as a world power, Columbia is dispatched to distant shores with great fanfare by a captivated public. What begins as a brand new endeavor of hope turns drastically wrong as the city soon disappears into the clouds to whereabouts unknown.

The player assumes the role of former Pinkerton agent Booker DeWitt, sent to the lost city to rescue Elizabeth, a young woman imprisoned there since childhood. He develops a relationship with Elizabeth, augmenting his abilities with hers so the pair may escape from a city that is literally falling from the sky. DeWitt must learn to fight foes in high-speed Sky-Line battles, engage in combat both indoors and amongst the clouds, and harness the power of dozens of new weapons and abilities.

“We are excited to expand the world of BioShock, which is one of the industry’s most critically acclaimed and beloved franchises,” said Christoph Hartmann, president of 2K. “We believe that Irrational Games will lend their meticulous attention to detail and unique storytelling expertise to make BioShock Infinite an incredible entertainment experience that will immerse new and diehard fans of BioShock alike.”

“But when it came to begin work on BioShock Infinite,” said Ken Levine, creative director of Irrational Games, “we only had one rule: No sacred cows. This game is both true to what people love about the series and unafraid to question every assumption.”

Levine continued, “In order to explore the floating city of Columbia, we needed an entirely new engine. To bring Elizabeth to life, we had to build brand-new animation and AI systems. To create wide-ranging indoor and outdoor firefights at 30,000 feet, we had to rethink, rebuild and expand the BioShock arsenal. The only thing gamers can be certain of is this: the rules of the BioShock universe are about to change.”
